XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. It's possible to execute a Velocity script without script right through the document tree. This has been patched in XWiki 14.10.7 and 15.2RC1.

Affected: Maven: org.xwiki.platform:xwiki-platform-index-tree-macro

### Impact

It's possible to execute a Velocity script without script right through the document tree.

To reproduce:

* As a user without script right, create a document, e.g., named Nasty Title * Set the document's title to `$request.requestURI` * Click "Save & View" * Reload the page in the browser

The navigation panel displays a document named with the current URL, showing that the Velocity code has been executed even though the user doesn't have script right.

### Patches

This has been patched in XWiki 14.10.7 and 15.2RC1.

### Workarounds

A possible workaround is to: * modify the page XWiki.DocumentTreeMacros * search for the code `#set ($discard = $translatedDocument.setTitle($translatedDocument.title))` * modify it into `#set ($discard = $translatedDocument.setcomment(''))`
